HIGH SPEED TELEGRAPHY

SUCCESSFUL COMMONWEALTH TEST.

A successful test in high-speed telegraphy by means of the Creed system was conducted between "The Argus" and the office of the " Sydney Morning Herald1' recently. The apparatus for the test had teen installed and operated by the Creed Company. Not- only can the apparatus apjid tan times as rapidly as messages may be transmitted by hand, but it eliminates much of the operating difficulty encountered in ordinary telegraphy. Tim message to be sent is typed by the operator upjn. a machine resembling a typewriter. Instead of recording the matter in typed words, however, this machine records the message as perforations on a strip of narrow paper. Though messages .are punched on a tape, this is done in terms of the ordinary Morse code' From tho punchingrnachine the tape is drawn through the high-speed transmitter, whence the messages are sent over a. land wire at the rate of 300 wordu a minute, and wlien they arrivo at'tho receiving station they rjiusp punch-holes in another tape exactly similar to that used at the transmitter. When punched, this tape is passed, into another machine, and, by a remarkable process, its perforations are translated into ordinary words which are recorded on a third paper slip. This Blip is then passed through a small appliance, which gives the unprinted side a coat of gum; and the slip while still wet, is' cutvinto strips, which are laid upon a sfteet of paper in the form, of a continuous typed message. The Creed apparatus at present in u«e between "The . Argud "I office and-'ths bydney Morning Herald " office is capable of transmitting at tho rate of 300 words a minute, and messages may be tent simultaneously at this speed over the one wire from Melbourne to Svdn~v and from Sydneyto Melbourne.
